We define a BPS Skyrme model, which is integrable, solvable and with solitons saturating a topological bound. When applied to nuclear physics, the model cures several serious problems appearing in the standard Skyrme model as well as in its typical generalizations. At the classical level, it qualitatively reproduces the main features of the liquid drop model of nuclei, providing proper relations between masses and radii of nuclei and the baryon number. In spite of its rather unusual form, the model also allows for the semiclassical quantization.
